uviPRovEMENT iN BEARINGS FOR CARD-GRINDERS.

Specification forming part of Letters Patent N o. 174,271, dated February 29, 1876; application filed Y February 10, 1876.

To all whom it may concern Be it known that of Philadelphia, Pennsylvania, have invented certain Improvements in Bearings for Card- Grinders, ot which the following is a specificacation: l

My invention relates to an improvement in bearings for the journals of the grindingdisks which-are applied to carding-machines for the purpose of sharpening the teeth of the card-cylinders; and theA object of my invention is to so construct these bearing that they may be permanently attached to the frame of' interfering with its 0perations. This object I obtain in the manner which I will now proceed to describe, refer-` ence being-had to the accompanying drawing, in which- Figure 1 is a side view, illustrating the application of my improved bearin g to the frame of a carding-machine, and Fig. 2 a vertical A represents one of the side frames of a carding-machine; B, the carding-cylinder; D, the doi'er, and E the grinding-disk, the latter present instance by power imparted to its spindle from the shaft ot' the doffer. As the disk is revolved it acts upon the teeth of' both cylinders B and I) in the usual manner. The bearing a has a removable cap, b, and is provided with a tubular projection, d, adapted to a sleeve, e, within which itis confined can turn freely) by means of a pin, f, projecting into a groove, c, in the said projection, the

vertically (but so that it bearing being thus connected to the sleeve by a swivel-joint. The sleeve e is adapted at its lower end to the vertical threaded portion of au angular arm F, a jam-nut, g, on which serves to secure the sleeve in any position to which it is adjusted. The horizontal portion of the arm F ings in the frame of the machine, to which it is secured so as to be readily adjustable longitudinally by means of nuts 71, h, adapted to the threaded end of' the arm. The grindingdisk and its spindle can be readily applied to or removed from the bearing by removing the cap b, without disturbing any other of the parts of the bearing, which, owing to the shape of the arm, can be allowed to remain on theframe, as it will not interfere with the Iordinary operations of' the machine. After the spindle of the grinder has been inserted into its place, it may be readily adjusted, either longitudinally, by means of the nuts It and h', or vertically for manipulating the sleeve'e.

I claim as my invention- The combination of the arm F, adapted to the frame of a carding-mach'ine so as fto be adjustable thereon, adjustable sleeve e, all as set forth.

In testimony whereof' I have signed my name to this specification in the presence of two subscribing witnesses.
